Qld man's body found with gunshot wounds

A Brisbane man's body was found riddled with gunshot wounds in a park south of Brisbane, police say.

Members of the public found the body of Mitchelton man Julian Neuendorf, 38, in the Logan River near the Logan Reserve boat ramp at Henderson Park, about 9.15am (AEST) on Friday.

Detective Superintendent David Hutchinson said Mr Neuendorf, who was known to police, had "sustained a number of gunshot wounds", probably on Thursday evening.

"He's had involvement with police over a number of years and he does have a few questionable associates," Supt Hutchinson told reporters.

"He has an assorted criminal history."

Det Supt Hutchinson said police believed Mr Neuendorf was murdered in the park.

Police would like to speak with anyone who saw anything suspicious in the Logan Reserve area on Thursday evening or who may have knowledge about the movements of Mr Neuendorf, who was last seen alive in Mitchelton earlier that day.
